EC number: 201-162-7
CAS number: 78-96-6
The test substance is not considered as hazardous for the environment. Therefore, a chronic test in Daphnia magna is not provided.
The long-term toxicity to aquatic
invertebrates was estimated using the model ECOSAR v1.11 implemented in
EPISuite v4.11 (chronic value = 8.5 mg/L). The substance was within the
applicability of the estimation model; but as long-term prediction by
the model has been developed based on a small data pool (training set: n
< 5), the modeled results have a high uncertainty.
In addition, the ACR approach
according to ECETOC (2003, Report no. 91) results in NOECs greater than
1 mg/L, based on the effect data of the acute toxicity study to aquatic
invertebrates (BASF AG, 1987; report no. 1/1131/2/87 -1131/87).
Annex IX Section 9.1.5 column 2 of Regulation (EC) No 1907/2006, it is
laid down that long-term toxicity testing on aquatic invertebrates shall
be proposed by the registrant if the chemical safety assessment
indicates the need to investigate further the effects on invertebrates.
According to Annex I of this regulation, the chemical safety assessment
triggers further action when the substance or the preparation meets the
criteria for classification as dangerous according to Directive
67/548/EEC or Directive 1999/45/EC or CLP-Regulation (EC) No 1272/2008
or is assessed to be a PBT or vPvB.
hazard assessment of the substance reveals neither a need to classify
the substance as dangerous to the environment, nor is it a PBT or vPvB
substance, nor are there any further indications that the substance may
be hazardous to the environment.
Annex XI Section 3, it is laid down that testing in accordance with
sections 8.6 and 8.7 of Annex VIII and in accordance with Annex IX may
be omitted, based on the exposure scenario(s) developed in the Chemical
Safety Report (“Substance-Tailored Exposure-Driven Testing”). In
accordance with Annex XI Section 3, it can be demonstrated in the risk
assessment that the manufacture and the use of the substance do not pose
an unacceptable risk for all environmental compartments as the risk
characterization ratios (RCRs) of the chemical safety assessment are
below 1 for all compartments (see Chemical Safety Report Ch. 9, 10).
a long-term toxicity test on aquatic invertebrates is not provided.
